On to step 4:
The number 658 fits into 3046 4 times, leaving a remainder of 414.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2632 from 3046 to get 414.
Append the next digit (9) from the dividend to 414 and continue with: 4149 / 658

Step 5:
658 can be fit into 4149 6 times, resulting in a remainder of 201.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 201 after subtracting 3948 from 4149.
Grab the next digit (5) from the dividend, add it to 201, then carry on: 2015 / 658

Advancing to step 6:
If we divide 2015 by 658, we get 3 and a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 463.0
Subtract 1974 from 2015 to get 41.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 658

Let's proceed to step 7:
658 can be fit into 414 0 times, resulting in a remainder of 414.
Record the quotient 0 as the next digit in the result. 
Result so far: 4630.0
Deduct 0 from 414 and we're left with 414.
Grab the next digit (3) from the dividend, add it to 414, then carry on: 4143 / 658

Moving on to step 8:
658 can be fit into 4143 6 times, resulting in a remainder of 195.
Put 6 as the next digit of the answer. 
Result so far: 46306.0
Deduct 3948 from 4143 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 9:
When dividing 1950 by 658, we get 2 with a remainder of 634.
Write down 2 as next digit of the result. 
Result so far: 46306.2
If we take 1316 away from 1950, we end up with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Moving on to step 10:
6340 divided by 658 is 9 with a remainder of 418.
The next digit of our result is 9. 
Result so far: 46306.29
The remainder is 418 after subtracting 5922 from 6340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 11:
658 goes into 4180 6 times with a remainder of 232.
The number 6 becomes the next digit in our result. 
Result so far: 46306.296
If we subtract 3948 from 4180, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 12:
2320 divided by 658 is 3 with a remainder of 346.
Use 3 as the next digit of our solution. 
Result so far: 46306.2963
The remainder is 346 after subtracting 1974 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 13:
If we divide 3460 by 658, we get 5 and a remainder of 170.
Use 5 as the next digit of our solution. 
Result so far: 46306.29635
The remainder is 170 after subtracting 3290 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 14:
1700 divided by 658 is 2 with a remainder of 384.
Write down 2 as next digit of the result. 
Result so far: 46306.296352
The remainder is 384 after subtracting 1316 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 15:
658 goes into 3840 5 times with a remainder of 550.
Use 5 as the next digit of our solution. 
Result so far: 46306.2963525
Subtracting 3290 from 3840 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 16:
658 goes into 5500 8 times with a remainder of 236.
Put 8 as the next digit of the answer. 
Result so far: 46306.29635258
If we subtract 5264 from 5500, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final result is 46306.29635258 with a remainder of 2.36e-07.
